function::sprint_ubacktrace - Linux
Overview
function::sprint_ubacktrace
is a command-line utility for printing the current stack trace in the form of a backtrace. It is primarily used for debugging and troubleshooting errors within Go programs.
Syntax
function::sprint_ubacktrace [FLAGS]
Options/Flags
| Flag | Description | Default |
|—|—|—|
| -c
| Only print contexts, not goroutines | false
|
| -e
| Don’t print receiver type in method calls | false
|
| -l
| Number of frames to print | 0
(unlimited) |
| -v
| Print file and line numbers | false
|
Examples
Print a backtrace of the current stack:
function::sprint_ubacktrace
Print a backtrace with file and line numbers:
function::sprint_ubacktrace -v
Print only the top 10 frames of the backtrace:
function::sprint_ubacktrace -l 10
Common Issues
- Encountering an "out of memory" error: This can occur if the backtrace is too large. Use the
-l
flag to limit the number of frames printed.
Integration
function::sprint_ubacktrace
can be integrated with other tools, such as:
- Debuggers: Use the output of
function::sprint_ubacktrace
to step through the call stack in a debugger. - Logging frameworks: Capture the stack trace and include it in error logs for further analysis.
